n a salt-and-water solution, salt is the solute and water is the solvent. vater is so abundant on Earth, it is a common solvent. However, other solvents ar often used in the laboratory, in industry, and even in the home, especially to fori solutions with nonpolar solutes. For example, you may use paint thinner, a non polar solvent, to remove grease from a dirty bicycle chain or from ball bearing The paint thinner dissolves (that is, it forms a solution with) the it from the metal. In general, polar solvents dissolve polar or ionic solutes, and nonpolar solvent dissolve nonpolar solutes. We describe this tendency with the rule like dissolves lik. This statement means that similar kinds of solvents dissolve similar kinds of so grease, removin utes. Table 13.2 lists some common polar and nonpolar laboratory solvents. TABLE 13.2 Common Laboratory Solvents Common Polar Solvents Common Nonpolar Solvents water (H20) acetone (CH3COCH3) hexane (C6H14) diethyl ether (CH3CH,OCH,CH3) methyl alcohol (CH3OH) toluene (C7H3) CONCEPTUAL O CHECKPOINT 13.1 Which compound would you expect to be least soluble in water? (a) CCI4 (b) CH;Cl (c) NH3 (d) KF of Solids Dissolved in Water: ake Rock Candy We have already discussed several examples of solutions of a solid dissolved i- water. The ocean, for example, is a solution of salt and other solids dissolver in water. A sweetened cup of coffee is a solution of sugar and other solids dis solved in water. Blood plasma is a solution of several solids (and some gases dissolved in water. Not all solids, however, dissolve in water. We already know that nonpolar solids-such as lard and shortening-do not dissolve in wate: Solids such as calcium carbonate and sand do not dissolve either. When a solid is put into water, there is competition between the attrootiu forces that hold the colid
